Installation
Before attaching the sensor to the flow meter, check for any potential clearance issues. It may be easier
to install the sensor after the flow meter has been installed in the line.
Do not use a wrench or Channellock® * to aid in hand-
installing the pickup sensor.
Whether the sensor requires a tool to install or is hand
installed, tighten to hand-tighten torque only. Over
tightening may cause damage to the sensor and as a result
it may not function properly.
Operation
Before installing, operating or attempting maintenance on a flow meter, read the appropriate
Maintenance Guide. As with any precision-engineered device, always operate and maintain the
equipment in accordance with the manufacturer’s instructions.
Overview
Flow meters are designed to measure the flow of liquids, which assist in cooling and lubrication. Always
close meters to air except when air is part of an automated purge cycle, such as certain paint systems. In
this case, the air segments are typically under 1 or 2 seconds and are interspersed with lubrication liquid
for a scrubbing effect; in addition, the air segments are short enough that the flow meter does not dry
out.
